The area under the PR curve is called Average Precision (AP). These precision and recall values are then plotted to get a PR (precision-recall) curve. Now, calculate the precision and recall e.g. Thus, in the column Acc (accumulated) TP, write the total number of TP encountered from the top, and do the same for Acc FP. Precision is the proportion of all examples above that rank which are from the positive class. In VOC metric, Recall is defined as the proportion of all positive examples ranked above a given rank. Note that if there are more than one detection for a single object, the detection having highest IoU is considered as TP, rest as FP e.g. Now, sort the images based on the confidence score. A prediction is considered to be True Positive if IoU > threshold, and False Positive if IoU 0.5 else FP. It is defines as the intersection b/w the predicted bbox and actual bbox divided by their union. To decide whether a prediction is correct w.r.t to an object or not, IoU or Jaccard Index is used. Most common are Pascal VOC metric and MS COCO evaluation metric. The different evaluation metrics are used for different datasets/competitions. Hope this helps.Read about semantic segmentation, and instance segmentation. You can either use shrink to back-up and then burn it to a program of your choosing or use the audio information off shrink to finish your movie whatever way you want. Click on each one and play the movie (arrow) each time until you figure out which is the audio you want for the movie. Click full disk, choose the movie, and right click in the preview window. The easiest way to find out for sure is to check it with the easy to use program dvd shrink after you've ripped the movie. They could be for director comments or visually impaired, but don't count on that. So in the Star Wars DVD all it changes is the opening crawl's language.ĭoes anyone know what those 2 unchecked DD stereo tracks are? I am thinking one is commentary and one is just the original audio in 2.0.ĭoes anyone know what those 2 unchecked DD stereo tracks are? I am thinking one is commentary and one is just the original audio in 2.0. The only use of this feature I can think of my is maybe a concert DVD which had a lot of different camera shots. I can't see many director's ever using this feature, especially when they have a vision of how a shot should be done. I have never seen or heard of a DVD with this angle feature prior to making this thread. Don't be silly yet you come off as aggressive? Not understanding and not making sense to me is one in the same. If it isn't, then maybe you can be forgiven for it. I'm assuming English is your first language. Instead, you belittled the people making the statements, and it turns out they were right. You could simply have said you didn't understand, but you didn't. Not understanding something someone says isn't the same as it making no sense. Could that be commentary? Why would it be unchecked by default?ĭon't be silly. There were also 2 unchecked DD Stereo English tracks. The French and Spanish subtitles were only for the alien dialogue. At the Jabba scene it said "Lucas" at the top briefly while Jabba calls out for solo. Eng sub 3 was also alien subtitles but there was one difference. Eng sub 1 was subtitles for all dialogue. After I finished the movie I went back to that scene and tried all 3 English subtitles. Other than some close up shots, it's not bad for DVD quality! One thing I noticed was there was no alien subtitles, like for the Greedo and Han dialogue. So I ripped the movie and watched the whole thing. Another says it has to do with language which also makes no sense. One user says it's different angles of the movie which makes no sense. I am confused as to what these means and from googling I found a post linked to this very forum. I left everything default except I unchecked angle 2 and angle 3. I found my Star Wars Trilogy DVD set and ripped A New Hope first.
